The exhaust flow from a turbofan engine operating at typical cruise conditions generates noise as turbulent flow interacts with the basic shock cell pattern. This can be a significant source of noise within the aircraft cabin. The proposed innovation is a new method for testing the acoustics of model scale turbofan engine exhaust systems at cruise conditions in a transonic wind tunnel. This would ...

CONVENTIONAL INTERCONNECT AND SWITCHING TECHNOLOGY HAS BEEN IDENTIFIED AS A LIMITATION IN HIGH THRUPUT PROCESSORS AND COMPUTERS. WAFER SCALE INTEGRATION IS ONE TECHNIQUE TO RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL RESOLVE INTERCONNECT PROBLEMS. METHODS OF INTERFACING TO WAFER SCALE DEVICES WILL REQUIRE OPTICAL INTERCONNECT TECHNIQUES. IMPLEMENTING COMMUNICA ...

HELMET MOUNTED DISPLAY (HMD) SYSTEMS PRESENT MANY POTENTIAL BENEFITS TO OVERCOME CURRENT DISPLAY LIMITATIONS OF EXTRAVEHICULAR SPACESUITS. IN THIS PHASE I EFFORT WE PROPOSE TO INVESTIGATE THE PRELIMINARY OPTICAL AND MECHANICAL DESIGNS FOR INCORPORATING AN HMD SYSTEM WITH THE EXTRAVEHICULAR MOBILITY UNIT (EMU). THE DESIGN GOALS ARE TO PROVE THE FEASIBILITY OF THE HUD SYSTEM ON THE EMU WHILE PROVIDI ...

LASER BEAM SCANNING IS REQUIRED TO SUPPORT SPACECRAFT TERMINAL RENDEZVOUS, STATION-KEEPING, AND DOCKING. CURRENTLY, ACOUSTO-OPTIC BRAGG CELLS OFFER THE BEST AVAILABLE MEANS OF SCANNING A LASER BEAM WITHOUT USE OF MOVING MECHANICAL PARTS. BRAGG CELLS, HOWEVER, ARE LIMITED BY THEIR SMALL ANGULAR RANGE, LOW SCAN SPEED, AND HIGH POWER REQUIREMENTS. WE THEREFORE PROPOSE AN ADVANCED INTEGRATED ACOUSTO-O ...

RECENTLY, MUCH ATTENTION HAS BEEN FOCUSED ON THE USE OF ILLICIT AND/OR DESIGNER DRUGS BY PEOPLE FROM ALL FACETS OF AMERICAN LIFE. ONE OF THE MOST POPULAR OF THE DESIGNER DRUGS ARE THE FENTANYLS WHICH ARE VERY POTENT AND VERY DIFFICULT TO DETECT IN BIOLOGICAL FLUIDS. THESE POTENT DRUGS ARE BEING USED BY PEOPLE FROM ALL SEGMENTS OF OUR SOCIETY INCLUDING HEALTH CARE WORKERS, MILITARY PERSONNEL, AND P ...

Moore's law states that computing performance doubles every 18 months. While this has held true for 40 years, it is widely believed that this will soon come to an end. Increases in performance coincide with decreases in scale on the computer platform. Dueto the small scale of computer components, both interference effects are starting to play a role in the development of new components. This impli ...

This proposal describes the design and creation of an interface for controlling multiple UAVs in a real-time situation. Named the Uninhabited Air Vehicle Management Interface (UAVMI), it is centered on a 3-dimensional graphical representation of theoperational geographic area. The operator is able to move a 3D cursor around within this geographic volume, selecting groups, paths, and targets in 3D ...

Ongoing logistical repair, maintenance, and resupply of space platforms will become a costly and potentially dangerous activity in the post Space Station era. This is primarily driven by the need for more frequent missions, and as the number of missions increases, so does the cumulative probably of failure in the launch, docking, and return phases of the mission. The best defense will be to make s ...

DUE TO RISING COSTS OF ALUMINUM, MILITARY CONTAINERS USING ALUMINUM EXTRUSIONS WILL BE STUDIED TO DETERMINE IF PLASTICS CAN ACHIEVE A COST AND WEIGHT EFFECTIVE REPLACEMENT OF TYPICAL PROFILES. BOTH THERMOPLASTICS (TP) AND THEMOSETS (TS) CAN BE MADE TO THE SAME PROFILES AS ALUMINUM EXTRUSIONS, BUT PERFORMANCE OF THE PROFILE WILL BE QUESTIONABLE. REINFORCEMENTS CAN BE ADDED IN THE FORM OF PARTICULAT ...
